Hi, we live in the country here in Australia and often watch the jets as they fly over us. Tuesday just gone I was outside with my hubby walking around and looked up as a jet was flying over us heading towards Adelaide(our closest city) flying south east when I noticed a silver round object flying behind the plane back from its jet stream. We could see the plane very clearly , the silver round object followed along and moved off to the left and then moved slightly to the right and then back to the left and disappeared behind the clouds.

I am nearly 50 years of age and have probably been lucky to have seen quite a few sightings of unexplained description in my life time.
